目的应用彩色超声多普勒诊断仪检测糖尿病患者的视网膜中央动脉、肾叶间动脉及下肢足背动脉,探讨糖尿病患者血管的血流动力学改变。方法应用彩色超声多普勒诊断仪检测30例糖尿病患者的视网膜中央动脉、肾叶间动脉及下肢足背动脉(并与30例健康自愿者对照)。结果糖尿病组视网膜中央动脉、肾叶间动脉及足背动脉的收缩期峰值血流速度及舒张期血流速度减低,阻力指数增高。结论糖尿病患者的视网膜中央动脉、肾叶间动脉及足背动脉的血流灌注不足,彩色多普勒超声可快捷、准确地检测动脉的血流动力学改变。
Objective To evaluate the hemodynamic changes of blood vessels in diabetic patients by detecting the central retinal artery, the interrenal artery and the dorsalis pedis artery in diabetic patients by color Doppler imaging. Methods The central retinal artery, the interrenal artery and the dorsalis pedis artery of 30 diabetic patients were examined by color Doppler sonography (in comparison with 30 healthy volunteers). Results The peak systolic velocity and diastolic velocity decreased in central retinal artery, interrenarterial artery and dorsalis pedis artery of diabetic group, and the resistance index increased. Conclusion The perfusion of the central retinal artery, the interrenortal artery and the dorsalis pedis artery in patients with diabetes mellitus is not enough. The color Doppler ultrasound can detect the arterial hemodynamic changes quickly and accurately.
